WitrynaH-C≡C-H + NaNH 2 (in ammonia or ether) → H-C≡C-Na (sodium acetylide) + NH 3: H-C≡C-Na + CH 3-I → H-C≡C-CH 3 + NaI: CH 3-C≡C-H + NaNH 2 (in ammonia or … WitrynaThis video is about going to an Alkane to Alkyne. This reaction is called Terminal Alkyne Elimination.
WitrynaPartial Reduction (Na/NH 3) Explained: When we use sodium metal dissolved in liquid ammonia ( dissolving-metal reduction) as the reagent for the reduction of alkynes, we obtain trans alkenes as the products. WitrynaThe reaction of aldehydes and ketones with ammonia or 1º-amines forms imine derivatives, also known as Schiff bases (compounds having a C=N function). Water is eliminated in the reaction, which is acid-catalyzed and reversible in the same sense as acetal formation. The pH for reactions which form imine compounds must be …
